Description

The Kubernetes kubectl cp command in versions 1.1-1.12, and versions prior to 1.13.11, 1.14.7, and 1.15.4 allows a combination of two symlinks provided by tar output of a malicious container to place a file outside of the destination directory specified in the kubectl cp invocation. This could be used to allow an attacker to place a nefarious file using a symlink, outside of the destination tree.

Affected configurations

• kubernetes kubernetes (>= 1.13.0 < 1.13.11) • kubernetes kubernetes (>= 1.14.0 < 1.14.7) • kubernetes kubernetes (>= 1.15.0 < 1.15.4) • kubernetes kubernetes 1.1-1.12
